I Need a New PSU, but I Have No Knowledge

TheDoulos · Jan 6, 2014

Hey all. My ASUS power surge shut-downs are indicating it's time for me to kick my old BFG Tech 650W PSU. Problem is, I'm on a budget, and I have no idea which PSUs/Manufacturers are good, or any other hidden things I'm supposed to consider when buying a PSU.

I'd like to stay in the $50-70 range. This is my build:

Asus Z87-Plus MOBO
Intel i-5 4430 Quad Core CPU
Geforce GTX 650 (manufactured by Gigabyte)
2 SATA HDD

I intend to use it for gaming. Can anyone help me out on a good, reliable PSU that's fits in my price range, and works for my system? Thanks in advance.

Will have much more than enough power. Perfect for your system. Also a VERY high quality and reliable unit. My girlfriend uses one in her i5 + hd7850 build.

450W is cutting it kind of close (since the GTX 650 Asks for a 450W Minimum). Are you ever looking to do any SLI?

I personally like this psu a lot. I always stick with corsair and I never run into trouble. You can change the wattage if you want but this is the best value.

tachybana :

First of all gtx650 doesn't even pull 100w and secondly it cannot be SLI'd.

450w is WAY more then enough. His computer will likely pull no more than 250 under full load. Like I said, my GF uses this same PSU for her i5 and 7850 build. Measured with a Kill-A-WATT, her computer pulls no more than 280w at MAX load.

The CX line form Corsair is made with inferior capacitors and is NOT typical Corsair quality. I would skip the CX line for sure.

I agree with the Antec 620W PSU suggestion from PepitoTV. The Antec VP-450 isn't even 80+ certified, doesn't have active PFC, and the output on the 12v rail is pretty low. I would avoid that one.

tiny voices · Jan 6, 2014

http://www.eggxpert.com/forums/thread/323050.aspx it is a tier 2 unit and the only reason it is not officially 80+ certified is because it does not have an active PFC. It has been shown on many hardware review sites to pass the test for 80+ SILVER. It is indeed a VERY high quality unit. The 620 is WAY more than his system needs and will barely run at 40% under full load. I promise his computer is never going to pull more than 250w like even 200w under MAX load.

Sorry, on the SLI. Guess i was following up on the wrong GTX 650 (was looking at the 650ti Boost). Good Catch

Thanks all! I appreciate all the feedback. This forum is incredibly helpful. I picked up the 450W Antec after doing a bit more research myself. I did a Wattage calculator, which put my PC at about 327ish Watts. It was cheaper than my budget, too, which was a big plus. You guys rock!

Are there going to be any adverse effects to not having an active PFC?

tiny voices · Jan 7, 2014

There are no adverse effects at all.

Also, there is no way you will pull 327w. That is pretty overestimated. 250w is about all it will possibly pull under max load.
