LOGISYS Computer PS480E12 480W ATX12V Power Supply

Pros: The fan is silent, the case is built well, the grille is nice, and the hookup is solid.

Cons: Unfortunately, this power supply is completely unusable. The second you plug it in, even while the PC is off, it emits a high frequency noise nonstop so loud, you have to wear earplugs next to it. Without it, you get dizzy and nauseous and feel like your head is going to explode. Keep in mind, if you can't hear ultrasonic frequencies, your kids and pets probably can so just DO NOT buy this power supply.

Overall Review: It's a shame reliability or quality isn't a factor because of that one defect. It looked like it would have been a nice power supply.

Pros: These power supplies are ridiculously cheap. So cheap that you should justly question if you should buy them. I build a great many PCs for friends, experiments, blog articles and compulsion. Since I don't care about any of the ones that won't be personal computers to someone, I use a lot of parts I would never otherwise use. I have used a lot of these PSUs and their black brother from another mother. They actually last for years 9 times out of 10 and when they fail, I have never had them damage another part.

Cons: They do sometimes fail sooner than you might hope. The ones that don't fail very early tend to last for years though. As stated in pros, I have also never had one damage another part when it did fail.

Overall Review: If you are building your first PC or can only afford to build one PC every 7 years or something, do not buy. There is maybe a 10% chance that you will have a bad one that only goes 6 months to a year and even 10% is too much if you can only buy one.

Pros: When it sparked up it didn't damage any other part of my computer.

Cons: This thing sparked up something fierce when i turned on my computer today.

Pros: Looks nice

Cons: Very loud,fan runs wide open.Only has 2 sata drive connectors on same line.had to add a drive connector for dvd,guess thats what happens when you buy cheap

Pros: N/A

Cons: I am now 2 for 2 on doa units for this model

Overall Review: I can't say i would recommend this brand to anyone.

Pros: Wires are nice and long, reason I had to purchase when switching cases. Delivers plenty of power for everyday computing or light gaming. 120mm fan was a plus, moves alot of air. Price was definitely right, especially for Logisys!

Cons: I decided not to knock an egg off for this, simply because of how cheap the unit is.... but I would have been happier if they threw some loom on the wires. At least on the main, makes for a sloppy, stock looking install.

Overall Review: Powers a Phenom II quad core, 2 SATA drives, 6, 120mm fans and a 8800GT GPU with no problem. Large fan keeps unit cool plus moves air through my case. The +12v rail is strong and unless you're using a high end GPU or multiple GPU's, this is plenty.

Pros: I've used more then 50 of these power supplies and only had 1 or two come back as bad. Quiet 120mm fan pumps out lots of air, no need for case fan.

Cons: Sometimes you have to cut some corners on the case to accomodate the power plug housing. Dremels are great for that!

Overall Review: Seems to work on 99% of desktops. Some custom builds may be more demanding, but those rigs don't tend to blow power supplies!

Pros: Works fine. Inexpensive 480W supply. 120mm fan. Single rail design makes it easy to know if you have proper power specs on +12V leads. For multi-rail supplies, manufacturers don't tell you which leads are connected to which rail. So if there are different Amp ratings on the different rails, you don't know with certainty if you are within specs on each rail. So you have to use the lowest rating for any single rail for all rails when calculating. This means wasted power and money because of needing to allow even more head room. Single rail eliminates this issue.

Cons: Label is upside down. ??? When mounted in case the label should be right side up. Oops! Looks silly in a clear side panel case.

Overall Review: Label states total combined power at 330W max 480W. Most power supplies state max power only. It is never a good idea to run a power supply for extended periods near max output. The reviewer stating this is only a 330W power supply is not telling the whole story. You can't compare this power supply at 330W to another that is rated at max power only. You must concider both nominal power and max power. If you aren't given nominal power then figure 2/3rds max as a ball park figure. Most drives, mbs etc are rated at max power anyway and don't list nominal power useage. You should add all the max power ratings for all installed devices and add 25%- 35% headroom to reduce power supply stress and improve worst case system stability. You should also make sure the power is where you need it. Some mbs require greater than 18A on the +12V leads for example. This is also a single +12V rail supply, which I prefer over multi-rail because the single rail is easier to calculate proper load dist.
