Our favorite Prime Day deals under $100

Razer Seiren Mini | USB| Cardioid | White, Pink, Black| $49.99 $37.99 at Amazon (save $12)
The Seiren Mini (see our review) is a lovely little lozenge of a microphone for casual users. It's a super simple mic, using the internals of more expensive options within a basic package—there's no mute button or volume knob. You can also get it in white or pink, and all the colors are discounted.

Razer BlackShark V2 Pro Wireless | 50mm Tri-Force | 12 - 28,000Hz | Closed-back | $179.99 $99.99 at Amazon (save $80)
One of the PC Gamer team's go-to gaming headsets. The multi-chamber driver design gives the BlackShark supreme clarity and almost an open back soundstage. For under $100, this is an outstanding wireless headset in black or white.

Razer DeathAdder V2 Mini gaming mouse | 8,500 DPI | 62g | $49.99 $34.99 at Razer (Save $15)
A lightweight and compact mouse with a great sensor. Though it's not got the highest DPI in the business, a lot of people swear by the ergonomics, and the build quality is decent. The DeathAdder shows up in deal roundups every year because it's hard to beat for the price.

Logitech G502 Lightspeed wireless gaming mouse | 25,600 DPI | 114g | $149.99 $89.99 at Amazon (Save $60)
We like this wireless Logitech mouse a lot (see our review of a previous version), but the $150 list price was a lot to spend on a mouse. These days, Amazon normally sells it for a little over $100, which is still pricey, but this Prime Day deal might bring the G502 into "time to finally replace that cruddy old wired mouse" territory for you.

Keychron K2 | 75% | Gateron | Tenkeyless | Wireless| $79.99 $63.99 at Amazon (save $16)
The Keychron K2 is a solid entry-level mechanical gaming keyboard. It has a nice build quality, four levels of backlighting, and can connect up to three devices and swap between them. It's one of our favorite budget wireless keyboards and right now it's at a nice discount.View Deal

Corsair Carbide Series 175R RGB PC case | Black | $84.99 $59.99 at Amazon (Save $25)
I like this case's style, or lack of it: It's got a tempered glass side panel to show off your PC's guts, but otherwise no frills except for a Corsair logo on the front. I could do without the logo, but the sails are better than the Razer snakes. This case regularly sells for $80 or more, so this is a genuine deal.View Deal

ASRock Phantom Gaming | 27-inch | 1080p | IPS | 165Hz | $179.99 $99.99 at Newegg (save $80 with rebate)
This is a 27-inch monitor for less than some of the smaller 24-inch panels on sale, and it still rocks an enviable IPS display, 1ms response time, and a 165Hz refresh rate. Fantastic for gaming on a budget.View Deal

WD Black SN850X | 1TB | NVMe | PCIe 4.0 | 7,300MB/s read | 6,300MB/s write | $79.99 $59.99 at Newegg (save $20)
This is our favorite SSD for gaming right now. Unlike the cheaper SN770, the SN850X encapsulates the best that PCIe 4.0 offers in terms of performance (see our review). That makes it a great fit for a boot drive with space to spare for your game library, and at this price, we're happy to pay the premium for its higher speed.

Sabrent Rocket 2230 | 512GB | NVMe | PCIe 4.0 | 5,000MB/s read | 3,700MB/s writes | $89.99 $74.99 at Amazon (save $15)
The 512GB drive is a great middle-ground for Steam Deck upgrades. Add the price of this and the $399 64GB Deck together, and you still save $160.01 over buying the top tier Deck. That's with well-improved read/write speeds, too.
