## Questions & Answers

**Q: Is this power supply 80+ certified?**
A: No. It is the best bang for their price & comes with a 1 year warranty. I mainly use it to refurbish or to sell low end rebuilds.

**Q: Can this fit with HP Pavilion 510c**
A: Physically measure your PSU in your current case. Many pc's use their own Proprietary design on their psu and/or board. Dell/HP and others alike Use their design on power supply size dimension to fit specific designs they have made. Custom built/DIY builds are flexible in many ways. 
And IMO, If building  your first pc try to get advice or assistance in the production of the computer. It’s better to build a cheap pc with room to upgrade than to buy one built for you without you in mind. I.E. All prebuilt setups. 
4k Alienware or 1300 pc custom. The 1300 Custom actually beat the Alienware @$4000. 

Essentially 1/3 of the price to custom build 
/W RGB remote  included for most case designs available. this gives us plenty of options like whether to add A gpu, how's the ventilation and /or liquid cooling.
If building a gaming computer I look to spend about 1/3 of the total  price on the graphics card / cards trying to factor cooling system into that figure.

**Q: How many Molex connectors does it have?**
A: this power supply is a 20+4 pin main connector not a 240 pin. this unit has 3 Molex 2 sata 1 4 pin for CPU 1 floppy disc drive

**Q: Can this work in a Lenovo think centre d6u?**
A: Most Lenovo Think Centres are slim design or All-In-One and will not take this power supply. You need the whole model for someone to answer this properly. Example Model  number Y00x 0000-D6U.

    Perfect replacement for Dell Studio XPS 8100
  

*by S***B on Reviewed in Canada on 30 April 2024*

I bought this to replace the dying 350W supply in my Dell Studio XPS 8100.At first glance I considered returning it because it did not appear to include the P4 motherboard connector. However, the arrangement is actually two P4 connectors that clip together. After separating them, I had the required P4 connector with one unused. There are other errors in the product description, and the actual connector configuration is:1x 24-pin motherboard, 2x P4 motherboard, 4x 15-pin SATA, 2x 4-pin peripheral and 1x FDD. Also included is an AC line cord.The screw holes lined up with my chassis, so installation was a breeze. It's quiet (certainly much more quiet than the dying fan on my old supply) and so far it's working well. Although its power rating is higher than my old supply, it is significantly lighter. I got 10yrs out of my old supply. Here's hoping this new one hangs in there as well.

    Reliable, Efficient Power in a Streamlined Package
  

*by J***N on Reviewed in the United States on 9 December 2023*

When the power supply on our legacy DOS box gave up recently, we were wondering if it's still even possible to get a brand new power supply which is compatible with the older ports on an ATX computer tower.  After finding this for a very reasonable price, I'm happy we took a chance because it paid off!  Here's some specific observations:Pros:Delivers 400W of solid power, more than enough for most PCsCertified efficient, resulting in less excess heat and (hopefully) lower electricity billsName brand - backed by support and warranty for peace of mindCons:Lacks some premium features like modular or wrapped cablesDoes not include super long cables, so best for a mid-size towerSo far, this has exceeded my expectations. While it doesn't have every bell and whistle, it nails the basics with reliable power and efficiency. Given the more than reasonable price point, solid performance, and support, it hits a sweet spot that offers great value. If you need a quality PSU that won't break the bank, especially for a legacy computer tower, the Coolmax I-400 is a great option!
