I was gaming for a couple hours and I start to hear this noise come from my psu. I've heard this sound before on another system and it usually does not end very pleasant.


Current Specs:
Intel 2500k
Sabertooth P67
Noctua NH-D14
G.SKILL Ripjaws X 8GB (2 x 4GB)


Dying PSU:
Tagan 800W (roughly 2 years old)

What power supply do you guys recommend for this particular setup that's around the 120~ price range that's modular?
 
Corsiar, Seasonic, Antec.

anything from them will be fine.
 
You might be able to get an HX750 from Ebay for around that much.

Or if you trust used ones, I'm sure someone from here can sell you an HX750 for around there too.
 
Just to answer a question (not making a recommendation):
http://www.guru3d.com/news/corsair-announces-enthusiast-series-tx-v2-power-supplies/ - Here is the updated Corsair TX v2 "enthusiast series." The pricing on Amazon is quite similar anyway.

http://www.jonnyguru.com/forums/showthread.php?t=7625 - and according to this, the TXv2 is using the same platform as the XFX core series (which is their budget series, though it still works well)

750w will handle any single-GPU setup. 850w will likely handle most AMD-based dual GPU setups. You're running p67 chipset, so I'd say dual-GPU is the most you'd see anyway (8x/8x).

Modular may not be "better," but I'd prefer the easier cable management. I have an older PC P&C 750w Silencer series which I got for $70 ~3 years ago. I wish I had a modular PSU... but because I use 9 SATA devices, I use almost all the cables anyway.

(OK, so maybe now I'm making a recommendation):
http://www.newegg.com/Product/Product.aspx?Item=N82E16817207001 - how is this XFX BE 850w PSU for $150 - $20 rebate = $130? If you're not in CA, then there's no tax. They have the 750w version for $20 less. Directron and provantage have decent prices on the same PSU's, and I think Directron may have some sort of general coupon code in the Hotdeals section (usually 2.5% or so).

seasonic x650 can be had for 109 when on sale at newegg. I have three so I might be slightly biased.
 
Extensive studying has shown there is virtually no difference between modular cables and hardwired cables that come off the same source.

750 is enough to power pretty much all dual GPU single CPU systems, unless you're running 20+ hard drives or 30+ fans, or you're extreme overclocking with a phase-change or similar system. 850 is usually extra insurance for a dual GPU system, but not necessary.

The XFX power supply is better than the original Corsair TX at the same price point in virtually every way (modular, better efficiency, better ripple control, etc). It is on par with the TX V2. Not to say the TX is a bad power supply, but it is outdated and overpriced compared to other power supplies.

modular isn't better.

Better in what sense? As far as usability is concerned, modular PSUs are most certainly better than PSUs with entirely fixed cables. From a performance standpoint, modular PSUs aren't better, but they also aren't appreciably worse.

Old? Still a solid power supply regardless of age. Almost 2,200 reviews and 5 egg rating.

Maybe I haven't kept up.. what has changed on these compared to the new ones? I know I would rather deal with Corsair for warranty over XFX.

The original TX750 has mediocre efficiency and ripple suppression, and is also not modular. I never said it was a bad PSU. However, nowadays there are newer and better units available, and there are certainly better deals.
 
Anytime you add the convenience factor you are looking for reduced performance. In this case the voltage drops across each connector in a modular supply. Which causes increased wattage output and excess heat buildup. Look at the older better PC Power and Cooling designs. They shy away from modular designs for those reasons. Buy what you want. I like 100% secure connections between my components and the PSU. Modular connectors are friction fit and not a 100% physical bond.

How much reduced performance are we talking about? Maybe 1 or 2% for the worst designed systems? Most likely less than .5%. Can you give us something to back up your statement? I highly doubt it, because there is lots of evidence to the contrary.

What is largely considered the best power supply on the market? The HCP1200 or AX1200. What are these power supplies? They are modular.
 
Well designed modular power supplies are fine. Fact is even inexpensive modular designs have no history of problems with modular connectors.
The largest reason many power supplies avoided modular was to avoid paying patent fees to Ultra.
Recently a group of psu companies won a case proving modular existed before Ultra filed for patent rights, or something similar. Patent revoked. You can expect to see far more modular designs.
Ultra seems to have changed its name too. The company.

This is entirely bs. If modular were such a voltage drop and heat buildup issue, there wouldn't be 80plus gold and platinum psus that are fully modular including even the mobo cable. Modular has almost zero issues with power loss. You're spreading 100% PC Power fud, especially since you mention the shitty PC Power company itself.

Yes, there is a voltage drop, in theory. Yes, that does lead to more power consumption, in theory. No, in practice the difference is not significant at all. This is quite obvious when you consider the fact that most 80Plus Gold PSUs and all currently available 80Plus Platinum PSUs are modular.

The older PCP&C units were good because they were based on good designs, not because they used fixed cables. I also think it's funny that you are complaining about the physical interface between a modular PSU and its cables, considering the fact that those same connections are the ones that are used to connect the other ends of those cables to the components they attach to. If you really want "100% secure connections", you better go ahead and solder all of those cables to the devices they attach to, or you're not going to get your wish.

Basically, the statements you're making are incorrect, and they have been debunked numerous times by numerous people. I suggest that you do a little research on these things before you go and spout off more PCP&C myths.
