Cheap PSU under load?

I replaced a Rocketfish PSU, And I have a question about it. The PSU I need to ask about is a Hunkey made Rocketfish RF-500WPS2, It is a 500 watt model that supposedly had a 600 watt peak. Anyway my brother put this computer together back in mid 2010, It is a MSI P55-GD65 Mobo, And i5 750 CPU, Ram is 8GB G.skill Ripjaw 1600, And two 250GB HDD 7200rpm sata, And the GPU ATI Radeon HD 5850, And for some reason the PSU installed was a Rocketfish RF-500WPS2 model. Anyway My brother upgraded, And put together a whole new i5 3550 rig, He then gave me his old i5 750 rig. Anyway after I got it, I noticed some games would lag/stutter, This would happen even if I lowered the graphic settings in the game. Later on I replaced the 5850 because the fan went out. And I put a GTX 650 Ti in. I still noticed Game lag/stutter, It was not as bad but still very annoying. Anyway later on I replaced the Rocketfish PSU after reading bad reviews on Huntkey PSU's. So I replaced it with a Corsair CX600. And after replacing the Rocketfish the lag/stutter in my games went away. Now my games run very nice and smooth, Even Battlefield 4 runs smooth. So my question is do some cheap PSU's have problems keeping up under load? Was the Rocketfish loosing amperage or something?
 
Not only do some cheap PSUs have problems delivering their rated power, nearly all of them do. Tons of cheap PSUs are on the market. Yes, if your card wasn't getting the power it needed it would not run very well among other things.

What he said. I have been using Corsair for years. Before that PC Power Cooling PSU's. I only get the best. If you don't you will have issues sooner then later.
