Looking for PSU

Solution
i wouldn't go for the brand, but the wattage should be fine.
for a brand i would go for corsair, evga, coolermaster or antec.
i personaly have the corsair one, and have not had a problem yet
proberly a 600-750Watt power supply will do. and no you don't need the 80+ rated psu, but most psu's have the 80+ rating (80+, bronze, silver, gold, etc).
Ususally when psu manufactures make a highly rated psu (example. 90+ gold), then they need to put quality components in to the psu to get the effiecieny rating, therefore they can be a better psu.
 


What do you think about this one http://www.amazon.com/FSP-550-Supply-Bronze-Raider/dp/B008O2HOKU/ref=sr_1_fkmr0_1?ie=UTF8&qid=1444042440&sr=8-1-fkmr0&keywords=Fortron+FSP+RAIDER+550W+88%2B+%2880PLUS+SILVER%29%2F+%2B12V+Single+Rail%2F+SATA+Array+Cable%2F+Silent+120mm+FAN%2C+Inaudible+19dBA+at+50%25+Load%2F+Active+PFC
or i need 600W atleast?
 
Your system will need a minimum of 500watts to operate. However, it is strongly recommended that you go for a 550w model, as its better to have a little headroom when it comes to power. If you go too high, such as 650-750 or more, you're actually paying more money for less, as PSUs become less efficient if you don't use a high % of their wattage.

Wattage is only one factor to consider when choosing a PSU; the others are efficiency and quality.

Many cheap PSUs are advertised at a wattage they will never give consistently or efficiently, and the quality of the components inside them can be dangerously bad, so it ALWAYS best to buy a more expensive PSU than risk blowing your entire system for the sake of a few £.

Efficiency is usually measured with a '80+' rating. You DO want this, as it is a strong indicator of quality and a higher rating means less money spent on energy bills. If a unit has no efficiency rating, avoid it. Bronze is a minimum you would want, though Silver and Gold are more preferable (platinum is usually overpriced).

Stick to trusted brands only; if youve never heard of it, don't buy it. Examples of good PSU brands are:
- Antec
- Corsair
- EVGA
- XFX
- Seasonic

My suggestion for your system would be the EVGA Supernova GS 550w.

It is a very high quality unit with an excellent efficiency rating (80+ Gold) which means it will provide consistent power to your PC with as little energy costs as possible. It is also modular, meaning you only plug the cables in you actually need which saves time and space when building.
