Would a 450w PSU be enough

TheRaviGaming · May 3, 2013

I was wondering if a 450 watt PSU would be enough for the following build:

ASROCK - 960GM-GS3 FX
AMD Phenom II x4 965 Black Edition
Sapphire Radeon HD 7770 1GB DDR5
Corsair Value 4GB 1600 MHz
160GB SATA 7200rpm

Thanks.

If you don't plan to overclock anything then a good quality 450w psu should be fine. If you do plan to overclock that Phenom II 965, it will use alot more power and I would recommmend a 5-600w PSU. If you did grab a good quality 600w PSU you would be fine to overclock and upgrade your video card in the future. At least you wouldn't have to replace your PSU all over again that way.

Corsair, Antec, XFX, Seasonic, PC power and cooling, are the brands you would want to look at for a quality unit.

http://www.tomshardware.com/reviews/phenom-x4-965,2389-10.html System using the Phenom II 965 at stock and overclocked, using a pretty power hungry video card(4870x2). Your 7770 will use about 1/3 of the power the 4870 uses, but as you can see if you add another card or go for a higher perfoming video card a 450w may not be enough. 600w to be safe and a little future proof, is my recommendation.

PS: A PSU is likely to last longer and be more efficient when you have a little headroom to spare. It's not a good idea to load a PSU close to it's maximum output IMO. The newer intel chips use far less power so you can get away with a smaller PSU, but AMD's chips have some catching up to do in total power consumption. Especially when overclocked.

minimal 500watt from good brand for handel many hardware HD7770, P2 965BE, fan, HDD will well .. 450W uknown PSu is very dangerous when system peak fulload .. don't say it from stock case.

thank's .. as i know yes .. jonny guru good for PSU dan Toms good for GPU, all out 450 highly enough for HD7770, but sometimes people often forget that the PSU has efficiency so need to be considered going forward and the other hardware, and fewer is better for it at the same price ..
