Quick psu questions

post #1 of 7
Thread Starter 
Ok so Im pricing out a new A10 build and decided on thishttp://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.1241773 which comes with a case and psu that i dont think ill use http://www.newegg.com/Product/Product.aspx?Item=N82E16811147099. My question is would this included "400"watt psu work for an additional 7870 that might be going in there down the road or is it HEC junk. Also, if it is, is this a decent 50$ fully mod psu?http://www.newegg.com/Product/Product.aspx?Item=N82E16817139048&nm_mc=EMC-IGNEFL073013&cm_mmc=EMC-IGNEFL073013-_-EMC-073013-Latest-_-PowerSupplies-_-17139048-L06B I couldnt find the real manufacture of it on corsairs webpage but it looks decent for 50$.

Thanks for any help you can provide

if you are REALLY hurting on budget, I'd recommend you stay with the 400w junk they included with the case while you save up another month or so for a real PSU biggrin.gif you don't need much for that system, but when it comes to PSU, quality > all. you won't find too many people that hang out in this section of the forum recommending a CX PSU smile.gif

my personal point of view is a PSU is a long term investment so you should get a good one. the PSU i'm using atm is almost 7 years old so i can appreciate the concept of buying quality for YEARS of trouble free service. the CX will be an upgrade to the junk they included in the package deal, but I would recommend you look into a capstone or something of that quality/value so your current and FUTURE builds will be protected while being serviced by that PSU.

only reason i considered it was because it was a fully mod psu for 50$. I have the money but this is going to be a bare budget build. Not saying i wont buy a decent psu but dont want to overspend alot on a build that only needs a 500watt psu. Any recommendations for something thats partially or fully mod(id really like this)?

as i mentioned. a PSU is something that you migrate from machine to machine. my current PSU has been with me for 3 complete builds now and my current machine is a far cry from the original machine the PSU was purchased for.

you can decide what you want to do with it, but my opinion is that a PSU is a long term investment and a quality PSU will absolutely outlive the usefulness of your current build. your PSU is the 1st and last line of defense for your system. anything/everything you plug into the PSU falls under the protection of the PSU. clean power is what keeps a machine running year after year.

what you need to decide is whether you care about this machine or not. if you don't care if the machine dies, then by all means, use the PSU that came with the case and just run it as long as it will. most of us at OCN feel our time is worth more then having to troubleshoot a machine when there are questionable components involved, so we tend to buy components that are not going to fail in the 1st place...

Normally Rosewill PSUs are OK, but the 400W model LC-8400BTX included with that case seems to be from L&C, according to the UL safety certification number E164554. L&C produces many brands of junk PSUs, including Codegen, Eagle, Allied, Deer, Hercules, and Fever. JonnyGuru.com has condemned their products. Here's a not-so-positive video review of another brand 400W PSU with the same LC-8400BTX model number, and its CSA safety certification, 233193, indicates it's also from L&C. The reviewer estimates it's capable of just 250W:

HEC can be junk but is usually not the very worst junk, and even their lowest quality products usually don't blow up stuff.

That Corsair 500W CX Builder Series PSU is very good and can put out that much power even at high temperatures, like 45C - 50C, and the modular ones have cables that are among the most flexible.

If there's one element to skimp on in a build, it's definitely NOT the PSU. A poor quality PSU will result in several unsavory issues, either at build time, or down the road, including:

- Increased noise, either from cheap fans that run at full speed 100% of the time, or from coil/capacity noise.
- Increased heat, wasted energy due to low efficiency designs and no power factor correction (PFC).
- Limited overcurrent protection vs. short circuits, etc. Most cheap PSU only have an input A/C fuse, and that will only blow if the PSU rating is substantially overloaded during a short.

The Corsair CX series isn't top of the line, but it's not garbage either. It is leagues better than the one that came with your case. I'm running a CX500M modular in my Fractal Node 304 media center PC with a Z78 ITX Haswell and a HD6770 board, SSD, and 2 DIMMS and it's more than enough. Very quiet too.

The stock 400W PSU in that case only has one PCIe 6-pin power connector. The 7870 boards I've seen require two. You would (at a minimum) require a Molex to to 6-pin connector, and very likely overload that PSU.

The Corsair CX is not great by any means it cheap for a reason

Stop recommending it only do it when A the buyer is broke and needs a PSU ASAP or B when there is nothing else thats better

Anyway the Rosewill Capstone has a 450 watts model
